LUBRICATOR.

SPECIFICATION forming part of Letters.Patent No. 294,315, dated February 26, 1884.

Application filed August 8.1883. (No model.)

To all whom/'it may concern,.-

Be it known that we, WILLIAM S. GEE-l -county of Cumberland and State of Pennsylvania, have invented certain new and useful Improvements in Automatic Lubricators; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in automatic lubricators for locomotive, marine, portable, stationary, and other enginesyand the object is to produce a very simple, effective, economical, and reliable lubricator, in which the oil or other lubricant will always remain in a iiuid state, andwill not congeal or become hardened, and therefore inoperative.

The invention consists in the construction and arrangement of parts of an automatic lubricator, as will be more fully described hereinafter, and more specifically pointed out in the claims, reference being had to the accompanying 'drawings and the letters of reference marked thereon.

Like letters indicate like parts in the different igures of-the drawings, in which- Figure l representsavertical section of our improved lubricator attached to a steam chest and cylinder of an engine. Fig. 2 is a section of part of the lubricating device for the piston-rod. Fig. 3 is a section of a lubricator connected tothevguides of the engines: Fig. 4 is a modified form of needle-valve.

In the drawings, A represents the reservoir or holder for containingthe oil, tallow, or other lubricating matter. It is provided with a removable cap, a, having a suitable head or handle for operating it by. In the lower part of this reservoir isv arranged a conical or other shaped vessel, B, connected at one side with a steam-pipe, b, leading to any desired part of the steam-space of the boiler.l Into the top of the vessel B is inserted la Siphon-shaped pipe, c, connecting at one end with the lubricant near the bottom of the reservoirjwhile its other end projects into an opening, d, Viuthebottom A.

To a suitable nipple, e, is screwed a needlevalve, C, by which the exact amount of lubricant can be regulated. The valve-casing of l this valve may be made of glass, or it may be provided with a sight-hole and glass, f, (shown lin Fig. 4,) so that the amount o f oil, duc., passla dial-plate on the-valve to indicate the position of the valve. In the side ofthe reservoir A is placed a lat glass indicator, z', to denote the amount of lubricant in said reservoir. Ihe lower end of the valve C is secured to a screwplug, D,which is screwed into the steam-chest.

VOn the opposite side or other part of the reservoir A is arranged a nipple, 7c, to which a pipe, Z, is attached. This pipe is provided with a ball-and-socket, swivel, or other joint, E, so that it can be turned in any direction, as desired. At the end of the pipe Z is placed a hollow ball or receptacle, m, which is filled with asbestus t convey the lubricant ontc the piston-rod of the engine. The end Z of the pipe'Z in Fig. l connects with the en d m of the pipe l. (Shown in Fig. 2.)

vIn the modication shown in Fig. 3 the reservoir A is attached to a horizontal pipe, F, which has branches Fl of T shape at each end,extending close to the guides ofthe engine, so that they can also be properly lubricated at all times. In the branches, or in both pipe and branches, is arranged asbestus fibers, to convey the lubricant by capillary attraction against the guides.

If desired, the conical vessel B and steamvpipe b and Siphon-pipe c may be dispensed with in this instance, and an ordinary lubricator may then be connected to the pipe F,. with its branches and asbestus filling.

Near the bottom of the reservoir A is arranged ascreen, n, upon which is placed loose asbestus o, to prevent any impurities that might bein or have settled from the lubricating material from being drawn by the Siphon-pipe into. the opening g, and'thus be forced into the steam-chest of the engine.. A wire screen is alsoy preferably arranged over the nipplekfor a similar purpose.

The operation is as follows: The reservoir A being attached to the steam chest, and the IOO steam-pipe b connected to the steam-space of .the boiler, the steam will fill the vessel B,and,

upon the principle of the injector, will draw the lubricant from the reservoir A and force it through the hole q into the steam-chest. At the saine time the lubricant passes through the pipe Z and lubrieates the pistourod. The amount of oil through the` opening g is regulated by the needle-valve C, and can lalways be observed through the glass plate f or the body of the valve. The steam serves to al- Ways keep the oil, tallow, or other lubricant in a iiuid condition and prevents it from freezing.

Having thus described our invention, what we claim, and desire to secure by Letters Pat ent, isl l. In alubrieator, a reservoir provided with a receptacle for steam connected to the steamspace and having a siphon-eonnection with the lubricant in said reservoir, and acting as an injector to force the 4lubricant to the desired place, substantially as specified.

2. In a lubricator, areservoir provided with a steam-receptacle, and having a siphon-con- I the piston-rod, all substantially as speciiied.

nection with the lubricant in said reservoir, and acting as an injector to force the lubricating material regulated by a needlevalve to the desired place, substantially as shown, and for the purpose set forth. v

3. A lubrieator provided with a steam-receptaele,as shown,and having apipe provided with a universal joint and a receptacle for asbestus at its lower end for lubricating the pis ton-rod, substantially as described.

4. The combination of a reservoir, A, provided with a steainreceptaclc, B, connected to the steam-space of boiler, and by siphonpipe c to lubricant in rescrvoir,with the openings d and g, arranged substantially as set forth.

5. The combination ot' a reservoir, A, constructed, as shown, with the wire screen n and asbestus filling o, all arranged as and for the purpose specified.

6. The combination of a reservoir, A, pro- .vided with steam and siphon connections, as

shown, with a pipe, F, having branches F', and the guides of an engine, substantially as and for the purpose set forth.

7. ,The combination of a reservoir, A, provided with steam and siphon connections, as shown, with opening r/ and needle-valve C, provided with sight-glass f, all substantially as specified.

8. The automaticlubricatorherein described, consisting of reservoir A, steam-receptacle B, steam-pipe b, siphon-pipc c, opening d, needle-valve C, having sight-hole f, and handleh, provided with indicator, and a pipe leading to In testimony whereof we affix our signatures 1u presence ot' two witnesses.
